The following genetic analysis shows the origins of the indo-European patriarchal pastoral culture called Kurgan (from the tumuli used to bury the dead). This is very intriguing since the birthplace of Arian civilization is halfway between Europe and the Indus Valley. This culture, also mentioned by Archaeologist M. Ginbutas in his book on the disappearance of matriarchy in ancient Europe (attributed to the Kurgan invasion), was deeply rooted in the North of India, passing through Iran to all Europe, Italy and Greece included. Indeed, all European languages are of Indo-European matrix as Sanskrit.
Whether these Kurgan or Jamna were initiators of warlike pastoral civilization would have no doubt ... A curiosity in the North of India still exists a sacred river called Jamna ... Jamna's culture (about 3500-2500 BC) according to the researchers was a nomadic culture, originated between Caspio and Ponto, characterized by inmates in the famous kurgan (tumuli).
Jamna's culture developed in the late Neolithic Age, was a nomadic culture of the steppes, between Caspian and Ponto, characterized by inmates in the famous Kurgan. It is identified as the ancestral nucleus of Proto-Indo-European language formation spoken by native Indo-Europeans, Aryans or Aries, coming from the Caucasus region, probably between the end of the Neolithic and the beginning of the Copper Age.
